kenny knight told the washington post, scalise was his neighbor and came as a favor to him, and did not know about racial views of the organizers. he said -- "he agreed, believing it was going to be neighbors, friends and family. he saw me not as david duke's guy, but as the president of our civic association." well for more we head south to speak with mark potok, senior fellow at the southern poverty law center. he joins us from montgomery, alabama. his latest piece is headlined, "steve scalise's denials are not believable." welcome back to democracy now! why aren't they believable? >> thanks for having me, for starters. i mean, they are wildly unbelievable. worst of all, when steve scalise was in his 20's in a state representative, that was the peak of david duke's heyday. duke ran for senate in 1990. he ran for governor in 1991. in both cases, he got the majority of the white vote in louisiana.
